Abstract

Pengolahan lahan kering yang dilakukan oleh petani kentang ditanami tanaman kentang sepanjang tahun. Seiring berjalannya waktu maka lahan kering di Dieng mengalami degradasi lahan. Penelitian ini bertujuan untuk menganalisis strategi adaptasi petani Dieng dalam pengolahan lahan kering di Dieng. Penelitian menggunakan pendekatan kualitatif. Teknik pengumpulan data melalui wawancara mendalam, observasi, dan studi dokumen. Hasil penelitian menunjukkan bahwa strategi adaptasi petani di Dieng meliputi strategi fisik, ekonmi dan budaya. Namun, dalam melakukan strategi adaptasi fisik, petani Dieng cenderung melakukan strategi yang bertentangan dengan prinsip ekologi sehingga menimbulkan dampak bagi petani dan juga lingkungan sekitar. Dampak positifnya petani memiliki peningkatan dalam segi ekonomi dan dapat memenuhi kebutuhan hidup mereka sedangkan dampak negatifnya yaitu lahan kering di Dieng terus mengalami kerusakan.For decades, farmers in Dieng cultivate potato in their dry land. This study aims to This research aims to analyze the farmer’s adaptations strategies in cultivating dryland in Dieng. This research uses a qualitative approach. Method of collecting data in this research is deep interview, observation, and documentation. The result of the research shows adaptation strategies farmers in Dieng including, physics, economic and culture. However, in applaying physical strategy, Dieng peasant tend to apply a strategy which was contrary to ecological principle. Consequently, it gave some negative impacts to the environment, such as land degradation strategy were enhancing economical condition and filling up the needs of the peasants.

Abstract

The world's energy supply is very dependent on non-renewable energy in the form of fossil fuels. This causes fossil fuels depletion and the need for alternative energy sources such as biogas. Biogas is produced from the fermentation process of organic matter with the help of anaerobic bacteria in free oxygen absence. This study aims to produce biogas from cabbage and tomato waste separately. Biogas production was carried out by varying feed concentrations of 100 g/L, 200 g/L, and 300 g/L for cabbage waste and 81.6 g/L; 215 g/L; and 237 g/L for tomato waste. This study consisted of 10 days seeding and acclimatization process, followed by a start-up stage using insulated anaerobic bioreactors. The largest methane from cabbage and tomato waste was 60% at a feed concentration of 200 g/L and 50% at a feed concentration of 237 g/L, respectively. The maximum growth rates (µm) for biogas from cabbage and tomato waste were 0.122 day-1 and 0.121 day-1, respectively.

Abstract

Di SMK Swasta Satria Bingai dalam hal pelaksaan pelayanan dan penanganan pendataan yang di lakukan oleh pegawai masih dilakukan dengan cara manual yang menggunakan microsof excel dan word yang dituliskan pada pembukuan sehingga memerlukan waktu yang lambat dan lebih lama dalam penyelesaianya. Untuk mengatasi permasalahan tersebut penulis membuat pemrograman Data Mining yang lebih mudah dengan dirancangya mengunakan metode clostring K-Maens dihapkan dapat mengatasi sistem manual yang sudah lama yang diterapkan pada Smk Swasta Satria Bingai.Tujuan pengembangan menggunakan Metode Clostring KMaens adalah untuk mempermudah dan meningkatkan keakuratan Pendataan siswa sehingga memudahkan dalam mencari data alumni siswa yang sudah lama. Dengan menggunakan jasa komputer, pencatatan data pendataan dapat dilakukan dengan cepat dan tidak memerlukanwaktu yang lama maupun ruang penyimpanan yang besar dan dapat mempermudah petugas dalam Pendataan alumni Smk Swasta Satria Bingai, sehingga tidak ada lagi kesalahan dalam pendataan bagi pegawai di Smk Swasta Satria Bingai. Dengan adanya Perogram ini data akan lebih akurat dan terpelihara sehingga dapat memberikan informsi dengan cepat dan tepat.

Abstract

Penelitian ini bertujuan untuk mengidentifikasi faktor-faktor yang signifikan berpengaruh terhadap persentase kasus bayi lahir dengan berat badan rendah di Sulawesi Selatan dengan menggunakan model regresi. Model regresi yang digunakan adalah model regresi klasik, dan model regresi spasial, yaitu model Spatial Autoregressive (SAR) dan model Spatial Error (SEM). Data yang digunakan dalam penelitian ini adalah data persentase kasus bayi lahir dengan berat badan rendah di 24 kab/kota provinsi Sulawesi Selatan tahun 2020 sebagai variabel respon, sementara variabel prediktor adalah persentase ibu hamil yang mengalami komplikasi kehamilan, persentase ibu hamil yang melakukan pemeriksaan rutin, dan persentase ibu hamil yang mengkonsumsi tablet tambah darah. Data ini diperoleh dari Dinas Kesehatan Provinsi Sulawesi Selatan. Berdasarkan hasil penerapan model regresi diperoleh bahwa tidak ada dependensi spasial antar wilayah baik dalam lag maupun errornya, sehingga model regresi klasik merupakan model terbaik pada persentase kasus bayi lahir dengan berat badan rendah di Provinsi Sulawesi Selatan dengan nilai koefisien determinasi sebesar 30%.  Adapun  faktor yang berpengaruh secara signifikan terhadap persentase kasus bayi lahir dengan berat badan rendah berdasarkan model regresi klasik adalah persentase ibu hamil yang melakukan pemeriksaan rutin, dan persentase ibu hamil yang mengkonsumsi tablet tambah darah.

Abstract

This study aims to analyze the concept of multicultural education from the perspective of Islamic Religious Education (IRE) in higher education. Multicultural education emphasizes respect for diversity in ethnicity, culture, religion, and social values as an integral part of the learning process. Within the context of IRE, multicultural education does not merely focus on cognitive aspects but also on cultivating tolerance, religious moderation, and appreciation for differences among students. This research employs a literature review method by examining books, scientific articles, and previous relevant studies. The findings indicate that the concept of multicultural education in Islamic teachings is closely related to the principle of rahmatan lil ‘alamin, the notion of ukhuwah (Islamic, national, and human brotherhood), as well as the values of justice and equality reflected in the Qur’an and Hadith. In the higher education setting, IRE holds a strategic role in embedding multicultural awareness through the integration of tolerance, respect for diversity, and social cooperation into teaching and learning practices. Therefore, the implementation of multicultural education in IRE can serve as a foundation for fostering social harmony and strengthening students’ national character amidst diversity in academic environments.
